Ultrasonic VaporiserProduct Description The Ultrasonic Vaporiser acts as an Air Purifier, Ioniser, Aroma Diffuser and Night Lamp. No more condensation, because there is no heating element, the ultrasonic wave technology works on the vibration of the water at such a speed that water vapours are dispersed into the atmosphere to add moisture to the environment. The unit stays cool to touch and the vapours are cool so it is perfectly safe to place anywhere in the room,
